similar to: Email client dowloads previously read messages as new during migration.

I am running dovecot 0.99. Everything works great; however, now I am looking at several different tools to convert mbox to Maildir. It seems the tools, mb2md.pl, perfect_maildir.pl, and others all do what they claim; however, when the messages are converted and they are stored in Maildir/cur, the email clients download these messages as new. This typically wouldn't be a problem;

A friend of mine passed me this[1] cause I'm recommending him Dovecot. My personal experience is very different to the one in that benchmark. I will appreciate similar links from those of you who had benchmarked Dovecot against other IMAP servers. I'm conscious that my personal experience is far to be a objetive comparison. I switched from UW-Imap/Mbox to Dovecot/Maildir a box with 45k

I just installed a limited test of RC10 last night. So far, all is great except for errors being logged for one user (out of about 150 users total). This one user has not yet complained or anything, but the log file has repeated entries of the following format for him (host and username changed to protect the guilty/innocent): Oct 24 06:13:02 mail dovecot: IMAP(username): file

I recently upgraded dovecot from 1.0.15 to 1.1.2 and since then I am getting the following types of things in the logs: Aug 21 17:23:13 mail1 dovecot: imap-login: Login: user=<myuser>, method=PLAIN, rip=172.16.78.20, lip=172.16.78.22 Aug 21 17:24:01 mail1 dovecot: Panic: IMAP(myuser): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed:

Hi, This small mail to share my observation about a recent move of mailboxes between two servers and ask about explanation and/or improvement about UIDL in dovecot. SV1 : Dovecot 0.99.14 / Red Hat Fedore Core 4 SV2 : Dovecot 1.07 / CentOS 5.2 Mailboxes in /var/spool/mail on the twoo servers. Test will be done with outlook express with option "leave message on server" checked. Goal is

I'm advocating for a change in the IMAP specification to allow outgoing email to be sent over the same connection as incoming rather that having to separately configure outgoing SMTP email. There are two significant advantages to this concept. 1) It would greatly simplify setup for clients as they would only have to configure one connection rather than two. 2) Spam reduction by

Hi Folks, How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz processor and 2GB of RAM would do a business with 600 users? This server will have a 100Mbps link to the net, however it will be access by the business using a couple of ADSL lines (Roughly 7Mbps each). This machine will also be running Postfix Your help is appreciated Cheers Jonny

Hi everyone! What's the best filesystem to use for the mail spool? I'm debating between Debian with xfs or FreeBSD with zfs. I'm not sure which way to go. I'm migrating from cyrus. I have about 50 users so it's not a large setup. Cheers! Monika -- Monika Janek Systems Administrator, Side Effects Software Toronto, Ontario Canada 416-504-9876 x207 www.sidefx.com

Hi! I'm currently running Dovecot 1.1.8 on a HP server using CentOS 5.2 as my IMAP server, receiving mail from postfix, and also using squirrelmail as the frontend. As I look at upgrading the mail server, I'd like to change to a higher availability configuration (where the server can fail and I don't have to reconfig my imap users). For the SMTP that's easy, because I can

GlusterFs always strikes me as being "the solution" (one day...). It's had a lot of growing pains, but there have been a few on the list had success using it already. Given some time has gone by since I last asked - has anyone got any more recent experience with it and how has it worked out with particular emphasis on Dovecot maildir storage? How has version 3 worked out for

Hello, I want to setup dovecot with two postfix servers on three machines: - dovecot - with huge amount of disk space - where all user emails will be kept, - postfix1 - with greylisting, amavisd-new (spamassassin, clamav, etc), with mysql backend, - postfix2 - same as postfix1. MX priority will be set to the same value for both postfix machines. For now I don't know how to "glue"

Hi -- Today, I've learned who to disable incoming mail delivery to dovecot (accepted by postfix), temporarily. Now, I would like to know if there is a way to make a "doveadm kick -A" a permanent disconnect until one would allow reconnects, again? This should be done *without* shutting down dovecot or *extensive* re-configuration. A "doveadm block -u <joe> -m 'sorry:

Hi folks, I am currently evaluating Dovecot for deployment to ~200 software engineers (so, heavy email users); I'm hoping this list could provide wisdom about how best to do the configuration, evaluation and deployment, and what testing folks have done to determine whether dovecot is right for their site. Below I've listed the diffs between the dovecot-example.conf and our config.

Hello We are using dovecot 1.2.x. In our setup we will have 1200 concurrent imap users (maildirs) and we have 2xraid5 sas 15k diks mounted by iSCSI. The dovecot server (RHEL 5 x64) is a virtual machine in our vmware esx cluster. We want to minimize disk I/O, what config options should we use. We can "exchange" CPU & RAM to minimize disk i/o. Should we change to dovecot 2.0?

SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it. Some new SSDs use SATA 3 (6gb/sec) with 355/mb/sec read speeds and 215MB/sec write. Put these in raid 0 and it screams! Can you imagine how fast that would be? What would be nice is if new email were on faster drives with old email being

Working with a dovecot migration, I am curious what version (if any) of Dovecot (dovecot-auth) supports SMD5 and ldap-MD5 when using Dovecot -> OpenLDAP direct binding? Thank you! Eric

Hi, We are currently running Dovecot v1.1.6 on our servers, and are contemplating an upgrade to 1.2, or 2.0 soon. We are wondering how many organizations are still running a 1.1 version of Dovecot, and if anyone has any thoughts on this transition. Have you upgraded from 1.1 to 1.2? What are your experiences with this? Have you upgraded from 1.1 to 2.0 directly? What are your experiences this

Okay, been working with tripack, seems the most mature package for this. Got it to work well with their test data set - data(tritest). When i tried random numbers to explore further, i am getting some results that don't reconcile. example run this: library(tripack) y <- runif(100) x <- runif(100) vm <- voronoi.mosaic(x,y) plot(vm) par(new=T) plot(x,y,col='blue') when
